Ok, this game is all about spelling. The point is to spell the longest word you can, while not being the person ending the word. As soon as a viable word is spelled the game ends and another begins. Ok? this game is easier demonstraited than explained.

First, someone start a letter:

a

The next post adds a letter...

ac

and the next post add yet another letter...

act

*Beep* now they game is fished cause we spelled a word! The 3rd 'poster' ended the game because ACT is a valid word.

Ok lets give it a try.
